O-type Star
An O-type star is a hot, blue star of spectral type O in the Yerkes classification system employed by astronomers. They have surface temperatures in excess of 30,000 kelvins (K). Stars of this type have strong absorption lines of ionised helium, strong lines of other ionised elements, and hydrogen and neutral helium lines weaker than spectral type B. Stars of this type are very rare, but because they are very bright, they can be seen at great distances; out of the 90 brightest stars as seen from Earth, 4 are type O. Due to their high mass, O-type stars end their lives rather quickly in violent supernova explosions, resulting in black holes or neutron stars. Most of these stars are young massive main sequence, giant, or supergiant stars, but also some central stars of planetary nebulae, old low-mass stars near the end of their lives, which typically have O-like spectra. O-type stars are typically found in regions of active star formation, such as the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shell Star
A shell star is a star having a spectrum that shows extremely broad absorption lines, plus some very narrow absorption lines. They typically also show some emission lines, usually from the Balmer series but occasionally of other lines. The broad absorption lines are due to rapid rotation of the photosphere, the emission lines from an equatorial disk, and the narrow absorption lines are produced when the disc is seen nearly edge-on. Shell stars have spectral types O7.5 to F5, with rotation velocities of 200–300 km/s, not far from the point when the rotational acceleration would disrupt the star. Spectrum The shell stars are defined as a group by the existence of rotationally broadened photospheric spectral lines in combination with very narrow absorption lines. Emission lines are frequently present but not regarded as a defining feature. The exact spectral lines present vary to some extent: Balmer emission lines are very common, but may be weak or absent in cooler star ...

OzJet
Ozjet Airlines Pty Ltd was a airline, scheduled and air charter, charter airline with its head office in Tullamarine, Melbourne, Australia operating within Australasia from Melbourne Airport, Sydney Airport and Perth Airport. In 2008 the airline was sold to HeavyLift Cargo Airlines, and on 20 May 2009 it suspended its last remaining operations from Perth. In June 2009, OzJet was purchased by the Air Australia, Strategic Group. With the insolvency of Strategic Airlines on 17 February 2012 also OzJet ceased all operations. History Ozjet was first registered as a trademark to Peter Schott, a Fairchild Swearingen Metroliner, Metroliner pilot from New South Wales studying for his Master of Business Administration at Swinburne University in Melbourne in 2002. When the Paul Stoddart announced the idea of a Low-cost carrier, low-cost domestic regional airline, Ausjet Airlines Pty Ltd was formed. Schott and Stoddart realised the potential of adopting the Ozjet name and did so. In 2004 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emoticon
An emoticon (, , rarely , ), short for emotion icon, is a pictorial representation of a facial expression using Character (symbol), characters—usually punctuation marks, numbers and Alphabet, letters—to express a person's feelings, mood or reaction, without needing to describe it in detail. ASCII emoticons can be traced back hundreds of years with various one-off uses. The protocol as a way to use them to communicate emotion in conversations is credited to computer scientist Scott Fahlman, who proposed what came to be known as "smileys"—:-) and —in a message on the bulletin board system (BBS) of Carnegie Mellon University in 1982. In Western countries, emoticons are usually written at a right angle to the direction of the text. Users from Japan popularized a kind of emoticon called ''kaomoji'', using Kana, Japanese's larger character sets. This style arose on ASCII NET of Japan in 1986. They are also known as ''verticons'' (from ''vertical emoticon'') due to their re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salute
A salute is usually a formal hand gesture or other action used to display respect in military situations. Salutes are primarily associated with the military and law enforcement, but many civilian organizations, such as Girl Guides, Boy Scouts and the Salvation Army use formal salutes. Ordinary civilians also salute informally to greet or acknowledge the presence of another person, such as a tip of the hat or a hand wave to a friend or neighbor. Military salutes Throughout history, military organizations have used many methods to perform salutes. Depending on the situation a salute could be a hand or body gesture, cannon or rifle shots, hoisting of flags, removing headgear, or other means of showing respect or deference. Hand salutes Origins According to some modern military manuals, the modern Western salute originated in France when knights greeted each other to show friendly intentions by raising their visors to show their faces and show that they are not carry ...

Uniformed Services Pay Grades Of The United States
Pay grades are used by the eight structurally organized uniformed services of the United States (United States Army, Army, United States Marine Corps, Marine Corps, United States Navy, Navy, United States Air Force, Air Force, United States Space Force, Space Force, United States Coast Guard, Coast Guard, United States Public Health Service Commissioned Corps, Public Health Service Commissioned Corps, and NOAA Commissioned Officer Corps), as well as the United States Maritime Service, Maritime Service, to determine wages and benefits based on the corresponding military rank of a member of the services. While different ranks may be used among the eight uniformed services, pay grades are uniform and equivalent between the services and can be used to quickly determine seniority among a group of members from different services. They are also essential when determining a member's entitlements such as United States military pay, basic pay and allowances. Structure Pay grades are divid ...
